This doesn't work.

function jsTest(cellname)
{
document.all.cellname.bgColor = '#bbbbbb';
}


I get the javascript error 'document.all.cellname' is null or not and
object. I want javascript to "translate" the cellname into what its
value is, not the string cellname.

document.all[cellname]bgColor

It is pretty old school to be using document.all but I'll assume you
have a good reason for using it instead of giving the cell an id and
using document.getElementById(cellId).

needs an extra dot:

document.all[cellname].bgColor

=============

Better perhaps use a cell number or row/cell numbers?

var myCell = document.getElementById('myTable').cells[23];

var myCell = document.getElementById('myTable').rows[3].cells[5];

=============

and please look at and use css styles:

myCell.style.backgroundColor = '#ff0000';

myCell.style.padding = '1px 5px 1px 20px';

document.all[cellname].bgColor

ACK, as is using bgColor. CSS has been around for almost 11 years now.
